wayland: Check transient depth
Gdk Wayland backend traverses up the window tree looking for transiency
parents, but does not check for cycles when doing so.
As a result, if two or more windows are transient to each other, the Wayland
gdk backend will enter an infinite loop.
While this is clearly a bug in the application, gtk+/gdk should be more robust
and handle such errors more gracefully.
To avoid looping infinitely, add a transient depth and check that the parent
window in on a lower transient depth and exit the loop otherwise.
